MicroBlaze Soft Core

We briefly examined the Xilinx MicroBlaze around 2005 when we started working on the Xilinx Virtex-II Pro FPGAs. The SDK included the MicroBlaze compiler and core as a netlist. We compiled the MicroBlaze as part of the Digilent S3 demo project, as mentioned elsewhere on this site. The processor only runs on Xilinx devices to our knowledge, but there is no compelling reason to go that route compared to MIPS, ARM or a free core.
